DGP - Django graphene permissions

Permission system inspired by DRF

Installation

Install the latest release:

$ pip3 install django-graphene-permissions

Or using pipenv

$ pipenv install django-graphene-permissions

Usage

Permission definition

---

You can create new permissions by subclassing BasePermission e.g.

from django_graphene_permissions.permissions import BasePermission

class MyPermission(BasePermission):

    @staticmethod
    def has_permission(context):
        return context.user and context.user.is_authenticated
    
    @staticmethod
    def has_object_permission(context, obj):
        return True

This package provides predefined permissions :

• AllowAny : Allow any access.
• IsAuthenticated : Allow only authenticated users.

Node Permission

---

Subclass PermissionDjangoObjectType and define the permissions via the static method permission_classes that should return an iterable of permission classes

from django_graphene_permissions import PermissionDjangoObjectType
from django_graphene_permissions.permissions import IsAuthenticated

class ExampleNode(PermissionDjangoObjectType):
    class Meta:
        model = Example
        interfaces = (relay.Node,)

    @staticmethod
    def permission_classes():
        return [IsAuthenticated]

Mutation Permission

---

Apply the permissions_checker([Permission,...]) decorator to mutate e.g.

from django_graphene_permissions import permissions_checker
from django_graphene_permissions.permissions import IsAuthenticated

class ExampleDeleteMutation(graphene.Mutation):
    ok = graphene.Boolean()

    class Arguments:
        id = graphene.ID()

    @permissions_checker([IsAuthenticated])
    def mutate(self, info, id):
        instance = get_instance(id)
        instance.delete()
        return ExampleDeleteMutation(ok=True)

Query Permission

---

Apply the permissions_checker([Permission,...]) decorator to the field resolver e.g.

from django_graphene_permissions import permissions_checker
from django_graphene_permissions.permissions import IsAuthenticated

class Query(graphene.ObjectType):
    post = relay.Node.Field(PostNode)
    posts = DjangoFilterConnectionField(PostNode)

    @permissions_checker([IsAuthenticated])
    def resolve_posts(self, info, **kwargs):
        return Post.objects.all()

TODO

• Improvements
• Tests
• Add a PermissionDjangoFilterConnectionField
• Better docs
